1. GEOMETRIC MODELIG FOR FINITE ELEMENTS WITH MULTI-REGIONS AND PARAMETRIC SURFACES / MODELAGEM GEOMÉTRICA PARA ELEMENTOS FINITOS USANDO MULTI-REGIÕES E SUPERFÍCIES PARAMÉTRICAS
Este trabalho apresenta um ambiente computacional para modelagem geométrica aplicada à análise por elementos finitos usando multi-regiões e superfícies paramétricas representadas por NURBS. O principal objetivo é gerar modelos 3D para serem usados em simulações numéricas baseadas no Método de Elementos Finitos (MEF). Nessa proposta, a metodologia

2. Algorithm to determine the intersection curves between bezier surfaces by the solution of multivariable polynomial system and the differential marching method
The determination of the intersection curve between Bézier Surfaces may be seen as the composition of two separated problems: determining initial points and tracing the intersection curve from these points. The Bézier Surface is represented by a parametric function (polynomial with two variables) that maps a point in the tridimensional space from the bidim

3. MODELAGEM DE CASCAS COM INTERSEÇÕES PARAMÉTRICAS / SHELL MODELING WITH PARAMETRIC INTERSECTION
We present a methodology for modeling finite-element meshes defined on parametric surface patches. The idea is to build curves and generate meshes over the parametric patches built with these curves, which also connect adjacent meshes. The final model is a representation of all meshes combined into a single data structure. The basic tools to generate such me
